Although RIM currently appears to be bleeding out after many self-inflicted knife wounds, new leaked slides show that the company is still hard at work on fresh hardware to headline its BlackBerry 10 operating system. The slides shows two devices, the L-Series (London) full-touch screen device and its N-Series (Nevada) QWERTY keyboard-equipped sibling.

Although not much is known about the hardware inside the phones, the L-Series is said to feature a 768x1280 OLED display (356 PPI) and is 2.16" wide. The L-Series looks similar to the dev hardware that was shown off at the official unveil of BlackBerry 10.

The N-Series' screen size is obviously compromised by its physical keyboard and is limited to a 720x720 screen resolution (330 PPI). The N-Series is slightly narrower at 2.08".

For comparison, the iPhone 4S and Galaxy S III weigh in at 326 PPI and 306 PPI respectively.

According to N4BB, the L-Series could make its way to the market in September, while those looking for some physical keyboard action with the N-Series will have to wait until the first quarter of 2013.
